STORAGE-BATTERY BOX.

The present invention relates storage batteries, and more pertienlerly to the bos or container Construction olsueli.batteri-es.

Sonie oft-lie objects of the present invention are to provide an improved box for Stor-age batteries; to provide nieens for preventing storege battery boxes from leal:-

ing; to provide en improved ineens 'for seal ing die joints between tlie sides of :i storage battery box and tlie oever or oevers therefor; to provide ineens 'whereby the bzitteij,vv reid cannot leal; or seep ont by way ol e joint, betiveen a. sido ond (rover, wliieb iras opened up; to provide ineens to inerenso the-length oi' travel oi; iieid or [luid by ivny of the joint between the lizitteiflgf bei: rind tlie .lg-eel in ense or' e. ieailt :it suoli joint; to provide ineens 'for preventing e\;} o.nsion or si'irez1d ing dport of butte 'y Covers, side wells, or partitions; nini to provide other improveN inents will hereinafter appear.

the li v ierring totlie drawings, e storage `bail'- I box 1() is slioivn el tbe generally iie eepted rectangular forni and vvliieli may be t' wood, rubber7 or any other suitable innterial. As here sliown the box is divided by transverse partitions 11 into tliree cells, 'and cover plates 1Q are provided respectively for the Celis, es is the usuel practice io. suoli boxes, 1t will be understood 'that the eover plates 12 are 'provided with the usuel eireuit terminals 13 end iilling or inspeetii'in openings 14.v

in connection with the jointing ond seeling ol the cover plates wit-n tl'ie side Tells of the box, it irais been :iisf;'.f.iiiniry to rebbe?,

' groove encircling' i,

the inner top marginal edge of the box Walls and iilso to provide e, flange extending eireuinierentizilly about tlie outside of each cover plete that when the parts-are assembled the ledge formed by nthe rabbeting lies substantially in the plane of tiie bottom of tlie respective cover flanges end thus forms a. supporting seatv for said flanges. In ceri-ying out the present invention, the inner inerginiil top edge of the wells 15 oi the box 10 are rabbeted to form an inner circumferential ledge 17, and tbe/cover plates 12 are provided respectively with exterior continuous flanges 18 Whielr in `assembled eoiidition lie flush, or nearly so', `witli the -:iioresaid ledge 1'1".

For the purpose of more completely bonding)r the Willis 15 and plates 12 together to prevent opening up oi the joint between tliein, the ledge 17 `is provided with grooves 2O extending parallel tothe sides of the respective eelA und like grooves 21 are pr0- vided in 'tbe tops el the respective eells, and like grooves ere "novided in tlre tops of tile respective per ii 11. This Const-ruetion provides sin Viiefily continuous :ii eelil ln e similar manner eaeli cover pinto iiing'e 18 is prob vided with a. groove in its nig-3er surfaee,

Wliieli followsv tlie eontoiir'oi the Cover 'plate nud thus substantially parallele the groov 'lornied in tire. wnils and partitions'.

Willi the pui-ts in esseiobled condition as shown in 3, a sealing compound is poured into the space nett-veen the' box Walls 123 und the cover plates 12, and' W'henlset furnis n roniplete s'enl :for the eontents of the relis. linrl'lierinore, the setting of theeom` pound in tlie grooves 2G and 21 acts as a clump to unite the adjacent Wallond cover und resists -e`xpnnsion or forcestendng to cruise the box well to break away from the sealing; compound.

As e ineens tor reinforcing the joint between boi; wells. partitions and Cover plates,

and also :ini-lioriiio` the paris to resist part,-

ing iii-tion, e plurality of bridge members 24` are provided, ezieli consisting of ,a relatively flat body 25 liziving :i width substantially equal to the dis-:inne between the grooves Q() und :ind :'51 und ifi, :ind yprov'idtcd with iink ges EEG iii'riinired to sont in said grooves resin-viivelv. '.llius in operative position this liridgi'e iiieiiiliers ist are located at yenit-Libie 'interriilf-s filone' ilie grooves, with.4

their iliona-es heeled-in the adjacent.'-

'lil

grooves-'While the body portion 25 bridges the box and cover portion betvifeen Vthe grooves, .li/Then such bridge members are used between a side wall of the bon and a cover plate, the Width oi the body 25 and the distance between the flanges 26 is made to corresponde@ the distance between the grooves 2G and 22. lVhen these bridge meinbers 24 are placed', the sealing compound is run into the spaces surrounding the cover plates, and thus lille' the-grooves 20, 21 and 22, and enoascs .the members 2Liin their anchoring positions. 'The result is a complete unitary bonding of the side Walls, parti tions and cover plates, with the added strength derived from thc groove filled ledges and flanges.

In battery bones heretofore constructed, having a plain ledge bounding the inner top circumference of the box and surrounding the cover plates, it has been a common souri of trouble toihave the sealing compensi open up along the face of the box-Wall, du

to the fact that the latter either expands iT/1 p ingllush wit said ledge an covers re- 00 spectively for sald cell compartments, each away from the compound or works looseV through pressure on the sides of the box, and in consequence the acid seeps upwardly and out through the seam so formed. By the present invention Isuch opening up of the joint betweenthe -compound andthe walls of `the box is not only unlikely to happen because of the sealed joint between the flush ledge and flange but also because should be a spreading of the joint, it is practically impossible for the acid to iindits way to the outside of the casing. It will thus be apparent that a. complete unitary jointing of a storage box side wall cover and sealing compound' has been provided wherein all the parts are anchored and bonded together in a leak-proof manner, and also in such a manner that stresses tending to separate the parts are .ellectivelyl resisted.

While only a single form is shown in l which this invention may be embodied, it

is to be understood that the invention 1s not limited to any specific construction, but might be applied to various forms without departing from the ,spirit of the invention or the scope of the appended claims.

Having thus described my invention, I claim: f"

l. n.' storage battery boi: comprising straight-sided walls having an inner continuous peripheral ledge, a cover having a flange arranged .to procject toward and to said ledge, and means lor interlocking said ledge and said flange and sealing the joint therebetween.
